SPECIFICATION forming part of Letters Patent No. 657,504, dated September 1 1, 1900. Application filedd'nne 22, 1900. Serial No. 21,168. (No model.)

To all whom, it may concern: V

Be it known that I, FRIEDRICH ALBRECHT, a subject of the Emperor of Germany, residing at No. 379 Swanston street, Melbourne, in the Colony of Victoria, have invented certain new and useful Meansfor Coupling Pipes or Cocks to Fluid Mains, Branches, Receptacles, or Tanks, of which the following is a specification.

This invention has been devised to provide an improved means for coupling or attaching pipesor cocks to mains or branch pipes thereof and for fixing pipes or cocks to receptacles, such as tanks, cisterns, &c., particularly where such pipes, branches, mains, or receptacles contain water, gas, or other fluid.

In order that the invention may be made clear, Ihave described same with reference to the accompanying sheet of drawings, in which- Figure 1 shows a portion of piping in crosssection with the coupling applied to it. Fig. 2 is a longitudinal view showing the same. Fig. 3 is a plan showing the feet of coupling. Fig. tis a plan of under side of washer. Fig. 5 is a plan of under side of washer provided with a channel to receive a washer or packing. Fig. 6 shows vertical section through same. Fig. 'Zshows the coupling in elevation as applied to tins and the like. Fig. 8 shows the inside face of a detached foot of the coupling. Fig. 9 shows a plan of the under side of feet of coupling. Fig. 10 shows the coupling with cock attached.

I employ a metal coupling piece or pipeA, screwed at one end a and having a collar B or enlarged ring provided about its center to form a butt-piece or limitation stopper. At the back of this butt-piece a plain tubular construction 0 proceeds forashort distance, the distance being approximately the thickness of the main, branch pipe, or tank, &c., in and to which the coupling-piece is to be fixed.

The tubular coupling is formed of two 1ongitudinal sections, (see Fig. 3,) the back end of each terminating in left and right hand extension-pieces D, respectively. These extension-pieces or feet are preferably about one-half the width or diameter of the unscrewed portion of the tube, from which they branch off at right angles by about a length equaling the diameter of the tube. These pieces are of stout construction, it being against them that the whole strain of the coupling when secured in position will be iniposed. A hole is bored into the pipe or main E to which it is desired to attach the coupling, the eXtension-pieces introduced with their feet in opposite directions to one another, and the two halves brought together, so'that the ring B at the end of the thread rests'upon and outside the main, while the twoprojecting pieces D are on the inner side of the main, pointing inopposite directions to one another, but parallel with the length of the main.

Upon the limitation stopper-ring B two flats b are cutthat is to say, one on each halfso as to agree with a thick metal washer F, prefl erably of lead, and having two squared keys or blocks fformed therein, Fig. 4, to correspond with the flats on the half-rings. This washer is passed down on the tube-coupling and may be held in position by a lock-nut. In some cases the lock-nut may be dispensed with, as the pipe-connection piece or cock G can be screwed onto the coupling-piece A and brought down tightly onto the top of the washer, so as to make a water or gas tight joint.

.In some cases a thin leather insertion, white lead, or like filling may be placed between the lead washer F and the pipe of the branch or main E on which it is connected, or the bottom of said washer may be calked, so as to form a tight joint and prevent leakage. The

washer has its lower side shaped to correspond with the surface of the pipe or main or of the tank or receptacle, asthe case may be, upon which the coupling is to be fixed, and in some cases may be grooved to hold the packing, insertion, or filling H. K represents pipes coupled by my appliances. One of the sections has a pin a," which enters a hole in the meeting face of the other.

When applying my invention to tins or drums containing kerosene, or other similar receptacles or tanks, a sharp-pointed instrument having a diameter slightly larger than the diameter of the plain tubular end of the coupling may be driven into the tin or drum at the required position, so as to cause a perforation in and to which my coupling may be introduced in manner hereinbefore referred to inconnection-with'pipesand mains. This instrument may-be formed in one with the pipe-connection piece Gand have a length of flexible pipe G or a cock attached.

The coupling-pieces A havein their inner faces a grooved channel 0, such channel leadin ginto thegopen tubular passageof the'coupling. I

L being a leather-washer between it and the drum, 7 Figs; 1 and Zshow the coupling just prior, 1 to beingtightened up. A turn or two of the piece G will draw the'part 01 against the pipe.

E and close the parts together to form a wa= ter-tight joint. 7 1 Having now particularly described andasf certained the nature of my said invention and v in what manner the same is to be performed, I declare that what I claim is' 1. A coupling for pipes or cocks comprising two meeting tubular sections, each having a a foot arrangedto extend in opposite directions and on-oppos ite sides of arad-ial line running 1 parallel with the inner sides of said feet, substantially as described. 1

2. A coupling for pipescomprlsing two tubular sections, each havinga foot-piece and a threaded portion, a collar carried .by said 1 sections and a washer inclosi'ng said collar and interlocking therewith. to prevent the turning thereof, substantially-as-described. v

, 3. The means for coupling pipesor cocks to fluid mains, branches, receptacles or tanks comprising two meeting tubular sections each having a foot-piece arranged-to lie inoppo- V site directions to the other pipe and; having J represents a cockused in lieu of piece G, t

screwed, portion and stop-collar in tcombina- 'tionwitha lead washer F and abouplingpiece G substantially as and for thepurposes set forth;

4., Themeans for coupling pipes or cocks to fluid mains, branches, receptacles or tanks comprising two meeting tubular sections each 7; having a foot-piece arranged to lie. in opposite direction to the other pipe and having screwed portion. and stop-collar with flat port'ions' in combination with "lead washer F vyithco'rresponding fiat projections fand a coupling-piece G.substantially. as and for the purposes set forth. I In testimony whereof-I have signed my name-to this specification in the presence of two subscribing witnesses.
